Torrens-TRUCK.

To all whom it may concern:

Be it known that I, ARCHIE W. BAILEY, a citizen of the United States, residing at lVheeling, in the county of Livingston and State of Missouri, have invented new and useful Improvements in Tongue-'lrucks, of which the following is a specification.

This invention relates to tongue trucks especially adapted to be used in conjunction with binders or harvesters and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a tongue truck which when applied to a hinder or harvester will enable the said machine to make a short turn in order that its line of direction of travel over a field may be easily and readily changed.

With the above object in view the truck comprises a wheel mounted shaft which is pivoted in the stub tongue of the hinder or harvester. An arm is fixed to the upper end of said shaft and extends beyond one side of the stub tongue. Strips are secured to the forward portion of the stub tongue and project beyondthe end of the same. A bell crank lever is pivoted between the said strips and a rod connects one end portion of the said lever with the said arm. A draft tongue is pivotally connected with the other end of the bell crank lever and may swing vertically but is restrained from swinging in a horizontal direction with relation to the said bell crank lever. The bell crank lever is arranged to swing horizontally and consequently as it turns the arm is turned whereby the wheels connected with the shaft are directed over the ground.

In the accompanying drawing: Figure 1 is a top plan view of the truck. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse sectional view of the same cut on the line 3--3 of Fig. 1.

As illustrated in the accompanying drawing the truck is applied to a stub tongue 1 which in turn is suitably connected with the binder or harvester (not shown). A vertically disposed shaft 2 is journaled to the stub tongue 1 and the said tongue is supported at the forward end portion of the said shaft. An axle 3 is carried at the lower end of the shaft 2 and ground wheels 4 are journaled at the end portions of the said axle. An arm 5 is fixed to the upper end of the shaft 2:and projects beyond one of the sides of the stub tongue 1. Metallic Specification of Letters Patent.

Application filed January 10, 1914. Serial No. 811,465.

strips 6 are fixed to the upper and lower sides of the stub tongue 1 and the forward portions of the said strips project beyond the forward end of the said stub tongue. A bell crank lever 7 is pivoted between the forward ends of the strips 6 and is adapted to swing horizontally or approximately so but is restrained against vertical swinging movement. One end portion of the bell crank 1ever 7 is provided with a series of perforations 8 in any one of which may be engaged the end portion of the rod 9. An eye 10 is pivotally mounted upon the outer end portion of the arm 5 and the rear portion of the said rod 9 passes loosely through the said eye. A spring 11 is mounted upon the rear portion of the rod 9 and bears at one end against the eye 10 and at its other end against a stop 12 mounted upon the rear portion of the said rod. A stop 13 is also mounted upon the rod 9 and normally engages the forward surface of the eye 10. The spring 11 is under tension with a tendency to normally hold the stop 13 in engagement with the forward surface of the eye 10. Plates 1d are pivotally connected with the forward end of the bell crank lever 7 and may swing vertically but are restrained against horizontal swinging movement with relatlon to the said lever. The

said plates 14 are attached to the opposite sides of the rear end portion of a draft tongue 15.

A rod 16 is pivotally and adjustably connected at its forward end with the intermediate portion of the arm of the bell crank lever as best shown in Fig. 1 of the drawing. The rear portion of the rod 16 is slidably received in an eye 17 carried by the arm 5 and a nut 18 is adjustably mounted upon the rod 16 and is adapted to engage the eye 17 when the spring 11 is compressed and thus the arm 5 may be swung positively with the tongue 15 after the spring 11 has been compressed as a result of the initial swinging movement of the tongue 15 in a direction away from the grain.

If the forward end of the rod 9 is connected with the innermost perforation of the series of perforations 8 the arm 9 will be swung approximately in unison with the bell crank lever 7 as the same is swung by the draft tongue 15. If however the forward end of the rod 9 is connected with the outermost perforation 8 the arm 5 will be swung to a greater extent than the bell crank 7 as the draft tongue 15 is swung. That is to say that the rod 9 may be connected with the bell crank lever 7 so as to cause the arm to remain approximately at a predetermined relation with respect to the arm of the bell crank lever having the perforations 8 or the rod 9 may be adjusted along the portion of the bell crank lever having the perforations whereby the arm 5 will be swung to a greater degree than the bell crank lever as the tongue lfi is swung. By providing the spring 11 at the end of the rod 9 and by having the said spring bearing against the eye and also by providing the stop 13 upon the rod the arm 5 is caused 'to move positively with the rod when the said rod ismoved in a rearward direction but when the rod is moved in a forward direction the spring 11 may compress sothat the tongue "15 may swing slightly in a direc tion away from the arm 5 without turning the same. Furthermore a resilient connection is provided between the arm 5 and the rod '9. which permits the ground wheels to swing or turn under the tongue truck as they encounter obstructions at the surface of the ground and thereby relieve the structure of suddenjar. It will therefore be seen that a tongue support of simple structure is provided and that the parts are soarranged as to effectually turn the binder at the end of its line of travel in order that it may be readily swung around to be moved in a different direction.

Having described the invention what is claimed is 1. In combination with a stub tongue a shaft journaled in the tongue, wheels supporting the shaft, an arm fixed to the shaft and projecting beyond the side of the tongue, an eye pivoted upon the arm, a bell crank lever pivoted to the tongue, a rod connected at one end with the bell crank lever and passing through the eye and having a stop which normally bears against the eye, a spring surrounding the rod and bearing against the eye, a stop mounted on the said rod against which said spring bears, and a draft tongue pivotally connected with the bell crank lever. Y

2. in combination with a stub tongue, a shaft journaled in the tongue, wheels supporting the shaft, an arm fixed to the shaft mounted upon the rod behind the eye, a

coiled spring surrounding the rod and hearing at one end against the last mentioned stop and at the other end against the eye, and a draft tongue pivotally connected with the bell. crank lever for vertical swinging movement and restrained against horlzontal swinging movement with relat on to the sald 7 lever.

In testimony whereof I aliix my signature in presence of two witnesses.
